I'm now updating my kernel to see if there are any improvements, which I doubt because there's hardly any change in the repo. But I've filed a bug to keep the RPi guy informed. https://github.com/Hexxeh/rpi-firmware/issues/103 > > > I just hope it is not another HDD failure. > > Looks like a controller and/or driver problem. > The web echo on "UNKNOWN(0x2003)" is suspiciously unhelpful. > > Lets try google > sd "FAILED Result" DID_OK DRIVER_OK > Aha.

I guess I'll do the same. The other spare one has enough space. So I'm going to backup everything and try your verification example of dd below.
